" * Internally Rust is using a field (discriminant) to keep track of the enum variant.\n"
" * `Bar` enum demonstrates that there is a way to control the discriminant value and type. If `repr` is removed, the discriminant type takes 2 bytes, becuase 10001 fits 2 bytes.\n"
" * As a niche optimization an enum discriminant is merged with the pointer so that `Option<&Foo>` is the same size as `&Foo`.\n"
" * `Option<bool>` is another example of tight packing.\n"
" * For [some types](https://doc.rust-lang.org/std/option/#representation), Rust guarantees that `size_of::<T>()` equals `size_of::<Option<T>>()`.\n"
